I have recently purchased a Panasonic FireTV television. When attempting to download apps with Downloader, the app will not install. I get the pop message “Unauthorized APK installation detected. Please do not install performance benchmark APKs without permission from deviceprot@amazon.com” I have noted on other blog sites recently that this is not only affecting Panasonic televisions.
Do you have the option to unlock Developer mode? Also have you allowed “Unknown Sources”? Don’t know specifically if this can be done with the Panasonic but has to be done on a Firestick?
To open developers options on a firestick you have to click on about 7 or 8 times, then you can allow apps from unknow developers
Thanks for this. I am an experienced downloader and understand the process. I am of the opinion that it may be a Fire TV software problem and I am aware others have the same issue. I have contacted Panasonic for a solution.
Good luck there!
Same thing on my Insignia tv, will not let me use downloader, hook up an Onn 4k to it to download downloader and get my apps, under 20 buck’s at Wal-Mart
